Abstract

Tujuan dari penelitian ini adalah untuk melihat apakah penggunaan pembelajaran Problem Based Learning yang dipadukan dengan media Grocery Shopping dapat membantu siswa meningkatkan kemampuan pemecahan masalah matematika pada materi pecahan. Penelitian kuantitatif termasuk dalam penelitian ini di SD Negeri Salatiga 02, subjek penelitian adalah 27 siswa kelas IVA sebagai kelas kontrol yang menggunakan model konvensional dan 28 siswa di kelas IVB yang menggunakan model Problem Based Learning. Observasi dan tes digunakan untuk mengumpulkan data. Data yang diperoleh berdistribusi normal dan homogen, sesuai dengan hasil uji prasyarat. Hasil uji T-test menggunakan Independent Sample T-test dengan nilai 0,000 < 0,05 maka Ho ditolak yang menunjukkan bahwa terdapat perbedaan kemampuan pemecahan masalah matematika. Meningkatnya kemampuan pemecahan masalah matematis kelas IVB dengan memanfaatkan model Problem Based Learning dengan media Grocery Shopping telah dibuktikan, dengan hasil pengukuran awal 65,9 meningkat menjadi 86,0, dengan kenaikan sebesar 20%. Maka model pembelajaran Problem Based Learning berbantuan Grocery Shopping berpengaruh secara signifikan dan dapat digunakan untuk alternatif model dan media pembelajaran pada siswa kelas IV pada materi pecahan.

Abstract

Abstrak.Penelitian ini bertujuan untuk mengetahui Efektivitas penggunaan model pembelajaran kooperatif tipe Numbered Head Together (NHT) terhadap hasil belajar matematika siswa kela III A SD Negeri Salatiga 02 yang dilihat dari adanya perbedaan rata-rata pretest dan posttest. Jenis penelitian ini adalah pre-Experimental dengan variabel terikat hasil belajar matematika dan variabel bebasnya model pembelajaran Kooperatif Tipe Numbered Head Together (NHT). Penelitian ini menggunakan desain One-Group Pretest Posttest Design. Subjek penelitian sebanyak 28 siswa, 16 perempuan dan 12 laki-laki. Data yang terkumpul dari hasi pretest dan posttest dilakukan uji t berbantuan SPSS Windows Version 21.00. Selanjutnya dicari taraf signifikansi atau probabilitas [Sig.(2-tailed)] dengan α = 0,05 dan menganalisis thitung dengan mencari ttabel menggunakan Tabel t. Hasil penelitian menunjukkan model pembelajaran kooperatif tipe Numbered Head Together (NHT) efektif terhadap hasil belajar matematika siswa kelas III A SD Negeri Salatiga 02. Model pembelajaran kooperatif tipe Numbered Head Together (NHT) dikatakan efektif dikarenakan terdapat perbedaan rata-rata antara nilai pretest yaitu 50.00 dan posttest yaitu 68.30. Hal ini diperkuat dari hasil signifikasi atau probabilitas 0,05 > 0,000 dan uji beda t hitung lebih besar dari t tabel (-2,733> 1,703). Abstract. This study aims to determine the effectiveness of the use of the Numbered Head Together (NHT) cooperative learning model on the mathematics learning outcomes of grade III A students of SD Negeri Salatiga 02 as seen from the difference in the average pretest and posttest. This type of research is pre-experimental with the dependent variable is mathematics learning outcomes and the independent variable is the Numbered Head Together (NHT) Cooperative learning model. This study uses the One-Group Pretest Posttest Design. The research subjects were 28 students, 16 female and 12 males. The data collected from the pretest and posttest results were t-test assisted by SPSS Windows Version 21.00. Then look for the level of significance or probability [Sig.(2-tailed)] with = 0.05 and analyze tcount by looking for ttable using Table t. The results showed that the Numbered Head Together (NHT) cooperative learning model was effective on the mathematics learning outcomes of class III A students at SD Negeri Salatiga 02. The Numbered Head Together (NHT) cooperative learning model was said to be effective because there was an average difference between the pretest scores of 50.00 and the posttest is 68.30. This is reinforced by the results of the significance or probability of 0.05 > 0.000 and the t arithmetic difference test is greater than t table (-2.733 > 1.703).

Abstract

This study was carried out to investigate the integrated technology in Computer-Assisted Language Learning (CALL) class support classroom management strategies. The study employed mixed-methods and involved   27 students and a lecturer of a CALL class in an English Language Education Study Program. The data collection instruments were a questionnaire, interview guide, and observation notes. The data analysis was processed using descriptive statistics, particularly for the questionnaire results. Meanwhile qualitative analyses were conducted to process the interview results and observation notes. The results of the study showed that necessary relevant technology was integrated in the CALL class and it could support classroom management strategies by engaging students in learning, delivering materials efficiently, and creating an immersive learning environment using gamification through internet. Using computer to support learning is effective to create an immersive environment and to manage classroom. The use of computer in language learning is able to support classroom management for a lecturer inside or outside the classroom.
